Hi, I had an ubuntu server 20.04 with almost nothing installed and
decided to upgrade the server to install the latest version of iredmail (1.6.2)

I upgraded the server to ubuntu 22.04, restarted the server,
then I installed iredmail 1.6.2 from the link in the site (1.6.2.tar.gz)

I restarted the server again, and I can login to the iredadmin, roundcube, etc, but I can't send emails,

I have inistalled iredmail so many times and I have never seen this error.
When I send an email, I see this in the logs:
Dec 24 14:11:28 lserver postfix/amavis/smtp[19539]: connect to 127.0.0.1[127.0.0.1]:10026: Connection refused
Dec 24 14:11:28 lserver postfix/amavis/smtp[19539]: 4NfYYr184pz2cPkC: to=<usertest@gmail.com>, relay=none, delay=0.09, delays=0.08/0.01/0/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10026: Connection refused)

This made me realize amavis is not working

I see this when I try to start amavis (It's weird because I have another iredmail installed in another ubuntu 22.04 and  this server has the same permissions in folders and files)

sudo amavisd-new start
Error in config file "/etc/amavis/conf.d/05-domain_id": Insecure directory in $ENV{PATH} while running with -T switch at /etc/amavis/conf.d/05-domain_id line 7.

I also see this error when I execute this command:

I also have checked that the amavis can connect to the mariadb database and also all theother apps like iredmail and roundcube (I can create users in iredadmin and log in using roundcube, I just can't send or receive emails
because amavis is just not working )
